This was the ep that cemented Matt Smith as my favourite Doctor since McCoy. Eccleston and Tennant were intentionally less eccentric, less alien and more accessible for The Saturda

I thought about this too while watching this episode. I thought back to Tom Baker saying he would do things that were decidedly un-human since the character is an alien. Smith made me think that with little things he does, tasting the leaf, reacting with disgust at the idea of snogging someone everyone alive would snog, and various other little "alien" actions.
